Certain models of Canon and Nikon DSLR cameras have proprietary connectors for their wired remote control input. Until now, this required the modification of a compatible remote control in order to use these cameras with our DSUSB shutter control interface. Shoestring Astronomy now offers the DSCBL-11 cable for Canon N3 connector camera models and the DSCBL-12 for Nikon 10-pin connector camera models. These will allow you to use our DSUSB shutter controller without having to get a remote control modified.
